Prosecutor Christopher Minue alleges that Lowell police were responded to the area outside 11 Stevens St. at 1:20 a.m. A witness told police there was a verbal argument over a telephone that turned violent when Owusu pulled out a knife and stabbed the victim in the arm.

Police found a lot of blood on a nearby car, Minue said. The victim fled before police arrived and has been identified. Owusu also had injuries to his face and head.
